This paper compares two procurement models for refrigerator and freezer parts. It focuses on their impact on cost structure and supply chain resilience. The analysis covers five key dimensions: bargaining power, management cost, logistics efficiency, quality control, and hidden costs. The goal is to help global B2B buyers choose the

Abstract The foaming process of freezer insulation layers is a core factor determining energy consumption, thermal insulation performance and long-term operation costs of equipment. This paper systematically analyzes the technical principles, microscopic structure characteristics and thermal conductivity differences of four mainstream processes: high-pressure injection foaming, vacuum-assisted foaming, cyclopentane eco-friendly foaming,

In the vapor-compression refrigeration cycle of refrigerators, the evaporator is the core component that fundamentally determines overall cooling efficiency, temperature stability, and energy consumption. While the compressor provides circulating power, the evaporator undertakes all heat absorption and heat exchange work. The upper limit of a refrigerator’s cooling performance is completely
